Measuring Intracranial Pressure with Ultrasound

Intracranial pressure above 20 mmHg, as might happen from bleeding or swelling, often is a consequence of traumatic rain injury from several circumstances (e.g. car wrecks, explosions, sports injury).  But measuring that pressure can involve a catheter inserted in the skull.  Researchers at MIT, however, have developed a less invasive method that relies on an algorithm which justifies an ultrasound reading (transcranial Doppler) and blood pressure taken with a finger cuff. While this method is not quite as accurate as that from a catheter, it doesn’t require a hole in the head.             MORE
